Research Topics

Neurodegenerative diseases like Alzheimer’s disease are a growing public health concern. The extended and devastating course of these diseases, the increasing patient population, and the lack of therapeutic options all contribute to this pressing public health crisis. Our lab studies the ways in which genetic and environmental factors alter fundamental cellular pathways to increase susceptibility or improve resilience to neurodegenerative diseases like Alzheimer’s disease. We are pursuing these scientific questions with the ultimate goal of identifying novel therapeutic or preventative mechanisms for neurodegenerative diseases. Our research combines techniques from biochemistry, genetic screening, and neurobiology in human induced pluripotent stem cell-derived tissues.
